Compare the synthesis, storage transport of location of receptors and cellular mechanism of action catecholamine, thyroid, peptide and steroid hormones.
Peptide hormones are generated in the endoplasmic reticulum. Moreover, steroid hormones are generated in the endoplasmic reticulum and mitochondria.
What are peptide and steroid hormones?Peptide hormones are hormones composed of amino acids, whereas steroid hormones are composed of lipids.
Peptide hormones are generated in the ER and then transported to the Golgi apparatus to be included in secretory vesicles for secretion.
Steroid hormones aren't stored in secretory vesicles and are transported by using serum proteins in the blood.

what type of pitch typically has the greatest average speed?
Answer:
The fastball has the greatest average speed.
The four-seam fastball has a speed between 50-60mph. Hence, the fastball has the greatest average speed.
What is a four-seam fastball?A pitch in baseball is referred to as a four-seam fastball, rising fastball, four-seamer, or cross-seam fastball. It belongs to the fastball family of pitches and is typically the hardest (and fastest) pitch a pitcher can throw.
It has that name because four seams are visible with each spin of the ball as it is thrown. A few pitchers in the major leagues have been known to exceed 100 mph with their pitches. Frequently, it is contrasted with the two-seam fastball. The fastest and with the least amount of lateral movement in the air, the four-seam fastball is also the most desired throw for fielding.
Hence, the fastball has the greatest average speed.

The planets Hox and Blox are near each other in the Dorgon system. The Dorgons have very advanced technology, and a Dorgon scientist wants to increase the pull of gravity between the two planets.
Which proposals would the scientist make to accomplish this goal? Check all that apply.
decreasing the distance between Hox and Blox
increasing the mass of Hox
increasing the distance between Hox and Blox
decreasing the mass of Blox
increasing the mass of Hox and Blox
decreasing the mass of Hox and Blox
Answer:
decreasing the distance between Hox and Bloxdecreasing the mass of Hox and Bloxdecreasing the mass of BloxExplanation:
Decreasing the distance between Hox and Blox will make it easier to increase the pull of gravity between the two planets, because less gravity would be needed to increase the pull of gravity. Hope that made sense. Decreasing the mass of Hox and Blox will decrease the amount of gravity needed to make the pull of gravity stronger. Because decreasing the mass of hox and blox is one of the correct answers ( of course i can't be 100% sure because the grader may be looking for different answers than normal), I am assuming that decreasing the mass of Blox is an answer too. Hope this made sense and helped.
What causes the different layers in our atmosphere?
Answer:
changes in temperature that happen with increasing altitude.
Examine the layers of rock. Identify and explain which layer contains the oldest fossils.
Answer: D
Explanation:
The oldest layers are on the bottom, and the youngest layers are on the top. Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils. Fossils are once-living organisms that have been turned into rock, in which the shape or form of the organism can still be seen.
give brainliest i dont have it yet
In river valleys, cliffs, hillsides, and man-made exposures like quarries and road cuttings, sedimentary rocks of the appropriate age are exposed, Thus, option D is correct.
What is sedimentary rock?The bottom has the oldest layers, while the top has the newest layers. Sedimentary rock frequently contains a significant amount of fossils because sediments may contain once-living animals.
It is possible to see the shape or form of a once-living organism in a fossil, which is an organism that has been preserved in rock. The type of rock in which fossils are most likely to form is sedimentary rock.
The rock strata are named according to the historical period during which they were formed, and they are arranged from oldest at the bottom to youngest at the top.
Therefore, bottom layer contains the oldest fossils.

Scientists found a layer of rock with several different fossils in it, as shown in the image. Based on the model, which of these fossils are the oldest and which are the newest? Explain your answer.
LOOK AT THE PICTURE!
Answer:
Fossils generally helps in relative dating of rocks.
The Trilobites are considered the oldest in this rock sequence when we apply the principle of superposition of strata.
The principle states that "in an undeformed/undisturbed sequence of rock, the oldest is always at the bottom while the youngest is on top" .
This principle therefore explains why the Trilobites at the base are considered the oldest.
Answer:
Oldest would be D and Youngest A Obvi

Answer:
nonstriated, involuntary, and attached to the eyeball
Explanation:
They are smooth muscles (nonstriated) that are not controlled voluntarily. You don't contract those tiny muscles on your own will when you look at a bright light. It is also attached to the eyeball because it contracts to ensure the least possible amount of light gets to your eye.

What patterns in the data are relevant to deciding whether the species are the same or different, but do not support your claims? Why are these sources of data in general important to scientists in determining common ancestry?
Gene sequences provide one of the most compelling arguments for shared descent. Comparative sequence analysis looks at how the DNA sequences of several species relate to one another.
Is there a pattern to evolution?The patterns that evolution might take over time can vary. Predation pressures and environmental factors can influence how animals exposed to them evolve in different ways. illustrates the three primary types of evolution: parallel, convergent, and divergent.
What patterns may be utilised to determine shared ancestry?By contrasting the macroscopic appearance of diagrams or photographs, it is possible to deduce general patterns of relatedness among embryos of various animals. It is possible to find patterns of resemblance in the embryological development of many species using visual data.

A seagull flew 145 meters to the east at a constant velocity. It flew that distance in
10.0 seconds. What was its velocity?
What’s the answer ?
Given parameters:
Displacement of the seagull = 145m to the east
Time taken to cover the distance = 10s
Unknown:
Velocity = ?
Solution:
Velocity is one of the physical quantities. It is the speed in a specific direction. Hence, velocity is a vector quantity having both magnitude and direction.
So, mathematically;
Velocity = [tex]\frac{Displacement }{Time taken}[/tex]
Velocity = [tex]\frac{145}{10}[/tex] = 14.5m/s due east
The velocity of the seagull is 14.5m/s due east
Answer:
v=d/t=v=145/10.0=14.5m per second

Select the part whose main job is to store nutrients, water, and waste in an animal cell.
-vacuoles
-chromosomes
-mitochondria
-cell membrane
Answer:
A.) Vacuoles
Explanation:
A.) is correct because vacuoles are responsible for the storing nutrients, water, and waste.
B.) is incorrect because chromosomes are made primarily of condensed DNA. They exist to make DNA separation during nuclear division more efficient.
C.) is incorrect because the mitochondria is where cellular respiration takes place. This process is necessary for energy production.
D.) is incorrect because cell membranes do not store things. Rather, the cell membrane protects the inside of the cell, allows for the existence of a fixed environment inside of the cell, and facilitates the movement of molecules that wish to enter or leave the cell.
